From 6 to 21 weeks old 480 Rhode Island Red laying hens weighing initially about 350 g were assigned to 4 treatment groups and given to appetite diets with CP 14% (T1 and T2) or 16% (T3 and T4) and ME 2650 (T1 and T3) or 2750 (T2 and T4) kcal/kg. Egg production at 21 weeks old was greater in hens given 16% than in those given 14% CP.
